Earlier today Lindsay Lohan went to her court mandated alcohol education class with her sister Ali, and after that she went to Rite Aid, and later in the afternoon we caught her leaving a recording studio with a pal.

Lindsay looked fabulous as always (well, since she's been sober), but we noticed an odd mark on her left arm, and we're dying to know what it is! It looks like it could be a bruise or a massive curling iron burn, but my money is on a tanning cream experiment gone horribly wrong. Then again, if Lilo gets sentenced to a few days in jail tomorrow morning, I think it's safe to say that she's going to come back with stranger marks on her body!
